SCRAPER.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Application filed June 6, 1911. Serial No. 631,581.

To all whom it may concern:

Be it known that I, GEORGE M. BAKER, a citizen of the United States,residing at Garden City, in the county of Nassau, State of New York,have invented certain new and useful Improvements in Scrapers; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to new and useful improvements in scrapers andmore particularly to that class adapted for the purpose of scraping theceilings of rooms.

An object of this invention is the provision of a device of thischaracter which consists of a receptacle in which is mounted anadjustable guide for the purpose of receiving a blade and holding thesame in such position within the receptacle that the sides of the wallsand corners may be scraped, the said receptacle also having securedthereto a clamp adapted to lock the blade in its various adjustedpositions.

Another object of this invention is the provision of a scraper forceilings which is comparatively simple and inexpensive to manufacture,reliable and eflicient in use and readily adjusted.

lVith the above and other objects in view this invention resides in thenovel feature of construction, formations, combinations and arrangementsof parts to he hereinafter more fully described, claimed and illustratedin the accompanying drawings, in which Figure 1 is a side elevation ofmy improved scraper. Fig. 2 is a top plan view thereof. Fig. 3 is an endview thereof. Fig. 4 is a longitudinal sectional view taken on the line41 of Fig. 2, and Fig. 5 is a transverse sectional view taken on theline 55 of Fig. 2.

Referring to the drawings by similar characters of references throughoutthe several views, the numeral 10 designates generally my improved wallscraper which comprises a substantially rectangular shaped receptacle11, consisting of opposite side and end walls 12 and 13 connected attheir lower edges by a bottom 14. The end walls adjacent their uppersides and ends are apertured as at 15 for the reception of the reducedends of longitudinally extending bars 16 which are held within the saidapertures and against displacement by screws 17 which are threaded inthe reduced opposite ends thereof. A transverse supporting bar 18 havinglongitudinally apertured heads 19 formed upon its opposite ends forengagement with the rods 16 is located within the said receptacle andlongitudinally movable therein, while located upon the rod 18 fortransverse movement is a sleeve 20 having extending from its oppositeends the depending legs 21 of a U-shaped bracket 22 upon the upper faceof which is secured a guide plate 23, the opposite ends of which arebent upon themselves in spaced relation to said plate as indicated bythe numeral 2 1 for engagement with the head 25 of the blade or scrapperknife 26. The shank of this knife 26 is reduced at its opposite sides asindicated by the numeral 27 which shank extends through. a slot 28formed in one of the ends 13, the said slot being sufliciently greaterin width than the width of the shank to permit the lateral movementthereof for a purpose to be later disclosed.

A transversely extending bar 29 is secured to the outer wall of thereceptacle above the slot 28 and is provided in its opposite ends withthreaded apertures 30 for the reception of clamping screws 31. havingsecured to their upper ends milled heads 32, whereby the said clampingscrews may be rotated and moved through said apertures 30, while theiropposite ends are swiveled as indicated by the numeral 33 to a clampingbar 34. which extends parallel to the bar 29. This clamping bar upon theproper movement of the screws 31 may be moved into and out of engagementwith the lower face of the shank 26 thereby securely retaining the bladeor knife within the receptacle and against dis placement.

The terminal of the shank which projects beyond the end wall 13 of thereceptacle 10 has removably secured thereto a handle 35, while a thumbscrew 36 extends through a threaded boss 37 formed upon the sleeve 20for engagement with the rod 18 for the purpose of retaining the bladeagainst displacement after it has been laterally adjusted.

It will be obvious from Fig. 3 of the drawings that one of the end walls13 is cut away as at 38 which permits of the insertion of the hand ofthe user of the scraper into the receptacle for the purpose oftightening or loosening the thumb screw.

From the foregoing disclosures it will be apparent that upon theloosening of the said screw the clamping bar will be removed from thelower face of the shank which perlnits of the longitudinal movement ofthe blade through the receptacle owing to the sliding engagement of therod 18, while upon loosening the thumb screw 36 together with theclamping bar the blade may be moved laterally with respect to thereceptacle, which longitudinal and lateral adjustment permits the bladeto adapt itself to the sides and corners of the ceiling.

From the foregoing disclosures taken in connection with the accompanyingdrawings, it will be apparent that a scraper of the nature described isprovided which will fulfil all the necessary requirements of such adevice.

Having thus particularly described this invention what I claim anddesire to obtain by Letters Patent, is:

1. A scraper such as described comprising a receptacle having a slotformed in one end thereof, a pair of guide rods secured to the ends ofthe receptacle, a supporting rod slidable upon the guide rods, a guideplate adjustable upon the supporting rod, a blade slidable through theslot formed in the end of the receptacle and engaging said guide, meansfor clamping the blade against displacement and a handle secured to theblade.

2. The combination in a scraper such as described, of a receptacle,longitudinally extending guide rods secured within the receptacle, asupporting rod slidable upon the said guide rods, a sleeve slidable uponthe supporting rod, a U-shaped bracket carried by the sleeve, a guideplate secured to the bracket and provided with bent ends, a thumb screwengaging the sleeve for the purpose of retaining it in its adjustedposition, one of the end walls of the receptacle being provided with aslot, a bar secured to the end wall above said slot, a clamping baradjustably secured to the first mentioned bar, a blade slidable throughsaid slot and provided with a reduced shank and a handle carried by theblade.

In testimony whereof, I afiix my signature, in presence of twowitnesses.
